TB43 with and without HU-mCherry were cultivated in LB and examined in the flow cytometer and the plate reader.

Preparation of Glycerol Stocks

ONC of minicell-producing strains containing the constructs AL11 and AL13 were treated according to the glycerol stock generation protocol.

Preparation of ONC

5 mL LB+CAM were inoculated with TB43 AL11 & TB43 AL13 for an inducer assay.

PCR

4 PCRs were prepared. The first with primers iMC1, iMC2 and template pAB001, the second with primers iMC3, iILS5 and template pAB001, the third with primers iILS1, iILS2 and template pILS8. The fourth one was an extension PCR with the products of PCR 1 & 2 as templates.

CPEC

A CPEC was performed to build the sRNA encoding plasmids according to the CPEC standard protocol. One reaction used the PCR products 1 & 2 as template, the other one was performed with the product of the extension PCR.

15/09/13

CPEC

Due to a dissatisfying result, the CPEC from 15/09/12 was repeated. Additionally, the construct was built by a Gibson Assembly according to the respective protocol.

Transformation

The CPEC and Gibson Assembly products were dialyzed for 15 min each and transformed into electrocompetent NEB Turbo and chemocompetent DH5α cells.

15/09/14

Preparation of ONC

ONC of TB43 were prepared and then cultivated in 600 mL LB.

Purification of Minicells

To isolate the produced minicells, the TB43 cultures were centrifuged for 15 min at 4 °C and 4,000 rpm. The supernatant was filtered twice over 0.45 μm filters and once over a 0.22 μm filter. The minicells were washed from the filter and rebuffered into glucose-free M9 minimal medium.

Preparation of HPLC samples

Glucose was added to the minicell suspension. In steps of 1 min, samples were taken and quenched with acetonitrile.

15/09/15

Preparation of ONC

ONC of TB43, TB43 AL11 and TB43 AL13 were prepared and then cultivated in 600 mL LB, each.

Purification of Minicells

All cultures were treated according to the minicell purification protocol from 15/09/14.

Preparation of HPLC samples

A HPLC sample of the TB43 minicells was taken. Glucose was added to the culture, a second sample was taken after 5 min.

15/09/16

Preparation of ONC

An ONC of MG1655 as negative control was prepared and then cultivated in 300 mL LB.

Purification of Minicells

The culture was purified in the same way as the days before.
